If you're looking for an action-packed adventure on the water, why not go for a white water experience in the numerous rapids found in Sri Lanka ? This activity is great fun for first-timers and experts alike, with a wide range and grading of rapids on some of Sri Lanka 's more turbulent waters such as the Kelani river. Kitulgala in the hill country, southwest of Kandy provides an ideal base from which many white water rafting tours take place.  Tours can be arranged for anything from 1 hour to a half-day including lunch.
